DEVICE FOR BENDING THE TACKS OF LASTED SHOES.

Specification of Letters Patent.

Application filed March 9, 1914. Serial No. 823,519.

T 0 all whom it may concern Be it known that I, EUGENE L. KEYES, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Devices for Bending the Tacks of Lasted Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings inclicating like parts in the several figures.

This invention relates to devices for use in the manufacture of boots and shoes and particularly to a device adapted'for use in perfecting side lasting of a welt shoe.

In lasting the sides of a welt shoe by a machine such, for example, as that shown in United States Letters Patent No. 597,321, the tacks are partially driven to facilitatetheir removal during later operations on the shoe. It is also preferable to drive lasting tacks in a direction inclined inwardly, as explained in said patent, but'the shape of shoes having deep shanks makes it necessary to drive the tacks at a greater angle in the shank than along the sides of the forepart of a shoe. The upper, being under considerable tension, has a tendency to slip up the stem to or toward the head of a tack driven at such an angle as many shank lasting tacks must be driven and this causes the upper to pull away from the last and become slack. After the side lasting is completed it is the usual practice to tap the tacks, especially the shank tacks into more nearly upright position with the hand pincers but this takes considerable of the operators time and is unsatisfactory.

The object of the present invention is to improve the side lasting of welt shoes by providing a device adapted to bend the tacks inwardly with greater facility and in a more efiective manner than can be done with hand pincers or other devices known to me. For this purpose a tack bending device is provided which is so shaped and arranged that its periphery can be made to extend inwardly over themargin of a welt shoe bottom to engage and bend inwardly the upstanding portions of the tacks successively as the shoe and the device are moved relatively in the direction of the length of the shoe edge.

As an important feature of this invention the periphery or tack engaging face of the device 1s so shaped that it first engages the Patented Jan. 2, 1917, I

upper near the head of the tack which has the effect of causing the upper to slide down the tack toward a point nearer the hold of the tack in the last and relieve the strain of the upper on the tack which allows the tack to be bent more easily and without the danforth and explained in the following detail description of one embodiment of the invention, referencebeing made to the accompanying drawing, in which Figure 1 is a perspective of the device of the present invention, and Fig. 2 is a vertical sectional view of the device showing the operative relation between the device and the shoe. V

The device comprises a stand 2 on the upper end of which is rotatably secured by a stud 5 an inverted bell-shaped, or frustoconical, head 6. Secured to the rim of the member 6 is an annular ring 8, the outer face of which is inclined upwardly and backwardly, as shown in Fig. 2 to present a comparatively wide tack engaging face. A hole 12 passing through the lower portion of the member 6 and the stud 5 is provided to receive a pin 13 for preventing the rotation of the device on the stand 2. After the shoe has been side lasted the operator presents it to the device so that the nose or lower portion 16 of the ring 8 engages the upper at the head of the tacks and strips it from the stem of the tack and then by the further manipulation of the shoe engages and bends inwardly the upstanding portion of the tack. The shoe and the device are then moved relatively to operate successively on the remaining tacks.

In the use of the device on shoes having narrow shanks and in which the curvature at the shank is abrupt it is preferable to lock the device on the stud 5 to insure the correct manipulation of the shoe to bend the tack inwardly at right angles to the plane of the bottom of the shoe. 7

It will be observed that the tack bending head presents a continuous tack engaging face which projects beyond the body portion of the head and is so located with respect to the head that the shoe is presented to the device in inverted position or in the position it is held by the operator when being operated upon by the side lasting machine which eliminates any unnecessary manipulation of the shoe in the use of the device.

Having explained the nature of this invention and fully described a preferred embodiment thereof I claim as new and desire to secure by Letters Patent of the United States V I 1. A device for use in bending inwardly upstanding tacks projecting from the bottom of a lasted shoe and comprising a support and a bending device rotatably mounted on the support, said device being shaped and arranged to'extend inwardly over the margin of a welt shoe bottom and to present a tack engaging face adapted to bend in wardly the upstanding portions of the tacks successively as the shoe and the device are moved relatively in the direction of the length of the shoe.

2. A device for use in bending inwardly upstanding tacks projecting from the bottom of a lasted shoe and comprising a support and a tack bending head presenting a continuous, comparatively wide upwardly and backwardly inclined tack engaging face which projects beyond'the body portion of said head and is so shaped and so located, with respect to said body portion, that the tacks in a lasted welt shoe may be pressed successively into engagement with said face to bend them inwardly while the shoe is in inverted position, theprojection-of the face being such that the bulging portions of the side of the last are disposed beneath the said face.

3. A device for use in bending inwardly upstanding tacks projecting fromthe bottom of a lasted shoe and comprising a sup port and a tack bending head rotatably mounted on the support and presenting a continuous upwardly and backwardly inclined tack engaging face which is arranged to extend inwardly over the margin of a shoe bottom and first engage the upper and strip it down the tack stems and then bend inwardly the upstanding portions of said tacks successively as the shoe and the device are moved relatively in the direction of the length of the shoe.

4:. A device for use in bending inwardly upstanding lasting tacks along the sides of a welt shoe and having operating faces comprising an outwardly extending face adapted to project inwardly over the margin of the shoe bottom, an edge adapted to engage the upper and strip it down the stems of the tacks, and an upwardly and backwardly inclined face arranged to extend up the tacks and engage the heads of the tacks for applying pressure against the heads of the tacks when the shoe is rocked upwardly whereby the upstanding tacks are bent inwardly.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. I
